Abstract

PURPOSE: To prevent the permeation of suspension to the interior of a condenser, by using cooling water, hot water and steam in the cooling water side of the condenser, carrying out suspension polymerization for vinyl choride resin while suppressing the foaming in a polymerizer by controlling the cooling water, hot water, and steam.
CONSTITUTION: Cooling water, hot water, and steam are used in the cooling water side of a condenser attached to a polymerizer, and the temperature of the cooling water side is previously kept higher than polymerization temperature. The polymerizer is charged with pure water, a polymerization initiator (e.g., lauroyl peroxide), a dispersant (e.g., partially saponified polyvinyl alcohol), and vinyl chloride or a vinyl monomer (e.g., ethylene) mixture consisting essentially of it, polymerization is started, and the feed of the cooling water is started. After the middle stage of the polymerization, the feed of the cooling water to the condenser is regulated, to give vinyl chloride resin.
EFFECT: The formation of scale in the interior of the pipe and condenser is prevented.
